Explanation:
Formula for energy value is as follows.
E = 
where,
= 13.6
n = number of shell
So, at ground state energy of hydrogen atom will be as follows.
E = 
= 
= -13.6
Hence, for an ionized atom value of energy will be as follows.
E' = 
or, E' = 
Thus, we can conclude that total energy of the remaining electron in the ionized atom is
.
Those tails are called hydrophobic. You can note the etymology: hydro= water, phobi = fear, aversion, dislike.
Phospholipds' tail is a long non polar chain, made of Carbon and Hydorgens, that rejects water (a polar solvent) and is attracted to non-polar compounds (oil for example). That is why that tails can atract dirt.
Answer:
Explanation:
<u>1) Data:</u>
a) Solute: acetone
b) Solvent: benzene
c) n (solute) = 0.863 mol
d) mass of solvent = 500 g = 0.500 Kg
e) ΔTf = 8.84 °C
f) Kf = ?
<u>2) Formulae:</u>
- Depression of freezing point: ΔTf = m . Kf
- Molality: m = n (solute) / kg solvent
<u>3) Solution:</u>
a) m = 0.863 mol / 0.500 kg = 1.726 m
b) Kf = ΔTf / m = 8.84°C / 1.726 m = 5.12 °C/m ← answer
